What changed · 31 Oct 2026

Tension ticked up slightly after the Hellenic General Staff reported two mock air-combat engagements between armed Turkish and Greek F-16s over the Aegean on 30 October, alongside elevated UAV and NAVTEX activity. Rival Greek-Turkish NAVTEX notices over two separate undersea cable projects kept economic and maritime friction elevated, while diplomatic exchanges stayed routine around Greece's Oxi Day commemorations. No GNSS interference was reported.

  • Military posture: 6/10 · Greek MoD reported 2 mock air-combat engagements between armed Turkish and Greek F-16s during Aegean intercepts on 30 Oct.
  • Diplomatic / political: 4/10 · Greek consul in Istanbul restated Athens' rejection of Turkish continental-shelf claims at an Oxi Day event on 28 Oct; no démarche or recall reported.
  • Economic / informational: 5/10 · Türkiye and Greece maintain rival NAVTEX claims over two cable corridors (EMC and the Crete-Cyprus GSI); Cyprus's GSI survey NAVTEX missed its end-of-October target.
  • EW / SIGINT: 3/10 · No GPS/GNSS jamming, spoofing or signals interference linked to Greece, Cyprus or Türkiye was reported in the past 24 hours.
